Overview
The IMX2268C-TL is an InnoMux2-EP series offline zero-voltage switching (ZVS) flyback switcher IC from Power Integrations. It supports up to three constant voltage outputs or one constant voltage and one constant current output, designed for dimmable LED strings. The device features a 650V breakdown voltage and operates at a maximum switching frequency of 100 kHz. It delivers a maximum open-frame universal output power of 50 W and a peak universal output power of 80 W. The input voltage range spans from 90 V to 277 V. It is housed in an InSOP-24B package with a typical shutdown isolation of 4 kVAC.
Feature Summary
- Integrates zero-voltage switching technology for high efficiency
- Supports multiple output configurations including combined CV and CC modes
- Includes integrated diode functionality
- Designed for dimmable LED string applications
Applications
- Dimmable LED lighting systems
- Multi-output power supplies requiring constant voltage and current regulation
- Offline flyback converter designs
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with the InSOP-24B footprint during PCB layout. Confirm moisture sensitivity level handling requirements prior to assembly. Cross-reference the part number with the latest Power Integrations documentation to validate any recent design changes or obsolescence notices.
Selection Notes
Select this component for applications requiring simultaneous constant voltage and constant current regulation within a single flyback topology. The 50 W power rating suits medium-power LED drivers. Consider the 100 kHz switching frequency for magnetics size optimization. Verify that the 650V drain voltage rating aligns with the primary side stress calculations for the target input voltage range.
Part Context
This device belongs to the InnoMux2-EP family, which specializes in multi-output LED driver solutions. It integrates the power switch and control logic into a single package to reduce component count. The EP series emphasizes enhanced performance and reliability for professional lighting applications compared to standard flyback controllers.
Replacement Considerations
Check the official Power Integrations substitution guide for direct pin-compatible alternatives within the InnoMux2 series. Verify if variants like IMX2267C-TL meet the specific power requirements, noting its lower 36 W rating.
